Abstract
Enroute and Terminal Control Area simulation exercises involving certified bilingual controllers from Montreal Center have been conducted in order to develop procedures for the implementation of bilingual IFR control in the Province of Quebec. The enroute phase of the program was designed to determine the effect of bilingual control on controller performance and the supplementary procedures required in both a radar and non-radar environment. The effects of traffic load, language, and type of sector on communication characteristics, controller errors, and control effectiveness were also observed. In the terminal control phase, the effect of varying work load as a function of the runway-in-use was also included in the analysis of arrival and departure control. Aircraft simulators integrated within the simulations, initially by voice-link and later by data-link, enabled representative pilots from professional aviation associations to evaluate the simulation exercises and the proposed bilingual system. Independent exercises investigated bilingual control procedures in situations of an exceptional nature in the terminal and enroute sectors.
